Earth's lower mantle thickness
Did you know?
WebThe Earth's mantle is the widest part of the planet. It has a thickness of 2,900 kilometers. The majority of the mantle is made up of magma, a semi-molten rock. The rock in the top portion of the mantle is hard, but it becomes softer and melts as it descends. The mantle lies just beneath the Sima. Earth's mantle is a layer of silicate rock between the crust and the outer core. It has a mass of 4.01 × 10 kg and thus makes up 67% of the mass of Earth. It has a thickness of 2,900 kilometers (1,800 mi) making up about 84% of Earth's volume. It is predominantly solid but, on geologic time scales, it behaves as a viscous fluid, sometimes described as having the consistency of caramel. Partia…
WebThis deeper mantle dehydration of the slab perhaps makes the transition zone the largest potential reservoir for water in Earth’s mantle because its main constituent minerals, wadsleyite and ringwoodite, can incorporate up to ∼1 to 1.5 wt % H 2 O in their structures at mantle temperature .
